A water balloon with a glow stick on the inside, in a stocking, hung from trees, patio cover, or the ceiling. Same pin elsewhere said: "Put a glow ball in a white stocking and hang many from trees or the ceiling." But what are glow balls?

Actually tie a knot. They tied a fisherman’s knot - the strongest knot. The rope will break before the knot comes undone and the knot only gets tighter with pressure. Frame the knot and vows as a keepsake. WAY better than the usual candle or sand elements
